Until 2003 you wasnt possible to hold a helo and fixed licence concurrently.
CAD - in their wisdom - deemed it impossible for a pilot to be able to deal with the inherently different skills required!!
For some reason - and I dont want to speculate - this changed about 18mths ago. However they will only allow you to get a helo licence IF you have an offer of employment from a HKG based helicopter company.
Add to that the GFS, unofficialily, require you to be able to speak Cantonese and you get the idea that to gain a rotary licence in HKG is a local honour only.
Having said the above - after several run-ins with HKCAD over this issue...... the GFS pilots are all great chaps as are the pilots with heli-HK et al, its not their fault.......God knows what goes through the head-shed at CAD though!
Some CX pilots have recently gained HK CPL(H).....with the concurrence of CX..... but basically cannot use the licence in HK for anything other than joy flights.
So mate.............. the answer to your question is No!
PM if you need further info as I can put you onto people 'in the know'.
